Hello,

the CRT tube 240NB4 (green) is used in an old computer monitor. I have to
replace this tube. I found a C10M36P31 (alternatively shown in the diagram
for this is a 2728831) with the same dimensions. I do not have any data
sheets about these tubes. Does anyone know if I can replace the 240NB4 by
a
C10M36P31 or by the 2728831 ?

If you also have any data sheets for these tube, please send them to me,
thanks.

Regards
Karl-Heinz



In my experience if it'll physically fit then it'll usually work fine, of
course this is true only for the tube, not the deflection yoke.
